of the remaining observations. If this argument is NULL then no
(further) observation is excluded.

observations are plotted.

.rescalefct rescales, if necessary, x and y axis for use in plot
functions. More specifically, if scaleX is TRUE rescales x,
if scaleY is TRUE rescales fct(x) (otherwise leaves them
unchanges); to this end uses trafos scaleX.fct with inverse
scaleX.inv, resp. scaleY.fct; it respects xlim
and ylim (given in orig. scale), thins out the scaled values if
necessary and accordingly modifies slots xaxt, yaxt, and
axes of argument dots to indicate the new axes have to be drawn;
using the paradigm small letters to denote values on original scale and
capital letters on transformed scale, its return value is a list with
(thinned out) values of x and y, X and Y and modified dots.
.plotRescaledAxis plots rescaled axes according to logicals
scaleX, scaleY; to this end uses trafos scaleX.fct with
inverse scale.inv, resp. scaleY.fct, scaleY.inv;
it respects xlim and ylim. By default, ot produces the x axes according
to the values in argument X, and the y axes as an equidistant grid of
length ypts on [0,1] (on transformed scale); each of these axes, again
by default will have n tick values; these are however thinned out if
the come to lie too close to each other on transformed scale.
Instead of producing automatically chosen tick values, the user may explicitly
require x-ticks and y-ticks values on the axes, using arguments x.ticks
and y-ticks. This function has no return value.
.legendCoord produces, if needed (i.e., if coordinates are not
given as strings like "bottomright"), rescaled coordinates for the
placement of a legend.
.SelectOrderData, for data to be plotted into the graph,
performs two optional selections: a first selection on the unordered (original)
data (acc. to argument which.lbs) and a second selection according to
which.Order on the data remaining after the first selection and ordered
according to argument fct; the return value is a list with elements
data, ie., the selected/thinned out data, y, ie., the
values of fct(data), ind, ie., the indices of the selected data
in the original data (after possibly two selections), and ind1 the
indices of the data selected by which.lbs in the original data; in
addition also the non selected data, data.ns, the respective
y-values y.ns and the corresponding index elements ind.ns are
returned as list items.
.makedotsP and .makedotsLowLevel manipulate the ...
argument, deleting certain items and selecting items which can be digested by
plot, returning the manipulated list.
.cexscale rescales the point sizes of the points to be plotted;
the unscaled sizes are given in argument y, y1 in
case of several lines of points to be plotted may contain the
vector of the sizes of all points to be plotted in (e.g., including
those of the other lines of points). maxcex and mincex
are maximum and minimum of the raw rescaled sizes; cex is
a factor drawn from argument cex.pts by which the raw sizes
are rescaled before being returned. fun is the function
by which the rescaling is done; by default this argument is NULL
and in this case the function log(1+abs(x)) is used.
.getDimsTD returns the number of different coordinates to be plotted.
.producePanelFirstS for each graphical panel inserts
(if needed) x and y tickmarks for user-specific axes
into a panel.first expression.
.getX.vec produces the x-grid (on original scale) for each of the panels
and decides whether to plot lines or points.
.getXlimYlim produces panel-wise xlim and ylim arguments
as well as left and right endpoints of the x-scalas.
.prepareTitles produces the titles for the panels.
.getToDraw computes which panels are to be drawn.
.preparePanelFirstLast prepares the panel.first and panel.last
expressions for each of the panels.
